This is really cool. Simple media servers are I think are where it's at. I know lots of people like applications to handle managing their media (a la iTunes) but I really prefer this type of organization method myself...it let me be a lot sloppier with the media metadata while still being able to find stuff in large collections.

Being entirely selfish, I do wish audio servers would focus a bit more on what kind of audio they can serve up. Something with robust support for tracker (mod, s3m, xm, it, mtm, 669, etc), chip (most old 8-bit PCs), and game music formats (SNES, Genesis/MD, etc.) for old systems would be amazing and something I've long looked for as it would instantly open up millions of songs without requiring several terabytes of storage. Many libraries like FFmpeg support many of those internally, but software build on those libraries simply don't expose it.
